An array of four instrumented moorings covering an area of 150 km2 was in place approximately 40 km offshore in eastern central Lake Michigan during MayOctober 1984. Each mooring supported current meters at the depth levels 5,10,20,30, 50, and 100 m, and a thermistor chain between 6 and 46 m depth. The current velocity data were used to compute the divergence and curl across the array area at each depth level. Two or three events of large southeastward currents, north-south alternating wind bursts, upwelled thermocline, and increased positive divergence and negative curl were observed from mid-August to early September.
